Abstract

UN CONJUNTO DE PERNO DE FRICCION PARA ACOPLAR POR FRICCION UN ORIFICIO FORMADO EN ESTRATOS ROCOSOS. EL CONJUNTO COMPRENDE UN TUBO ALARGADO Y UN MECANISMO EXPANSOR ACCIONADO POR UN MECANISMO DE ANCLAJE MEDIANTE UNA BARRA O CABLE ALARGADO. UN MECANISMO DE RETENCION ES MONTADO PARA ACTUAR ENTRE LA BARRA O CABLE Y EL TUBO PARA EVITAR LA EXPULSION DE LA BARRA O CABLE DEL CONJUNTO SI LA BARRA O CABLE SE ROMPEN.  A FRICTION BOLT ASSEMBLY FOR COUPLING FRICTION A HOLE FORMED IN ROCKY STRATES. THE ASSEMBLY INCLUDES AN EXTENSIVE TUBE AND AN EXPANSOR MECHANISM OPERATED BY AN ANCHORAGE MECHANISM BY AN EXTENSIVE BAR OR CABLE. A RETAINING MECHANISM IS ASSEMBLED TO ACT BETWEEN THE BAR OR CABLE AND THE TUBE TO PREVENT THE EXPULSION OF THE BAR OR CABLE FROM THE ASSEMBLY IF THE BAR OR CABLE BREAKS.
